Step-by-step explanation:
What is the area of the trapezoid shown below?
Hello there!
Your answer is 180 units²
Step-by-step explanation:
[tex] \large \boxed{ \mathsf{ \frac{1}{2} \times sum \: of \: two \: parallel \: \times height}}[/tex]
The formula in the box is an area of trapezoid formula. We know the sum of two parallel lines which is 15 because 7+4 = 11 + 4 = 15
another 4 comes from parallel side. If both sides are parallel, they have same length.
The only thing that is missing is the height. The height can be found by using Pythagorean Theorem as you notice a right-angle triangle when splitting in half.
[tex] \large \boxed{ {a}^{2} + {b}^{2} = {c}^{2} }[/tex]
The formula in the box is Pythagorean Theorem for finding a length of right-angle triangle.
Given where a is opposite, b is adjacent and c is hypotenuse. (Note that c must be hypotenuse.)
Our a is missing
Our b is 7
Our c is 25.
From the formula and given lengths:
[tex] \large{ {a}^{2} + {7}^{2} = {25}^{2} } \\ \large{ {a}^{2} + 49 = 625} \\ \large{ {a}^{2} = 625 - 49} \\ \large{ {a}^{2} = 576} \\ \large{a = 24}[/tex]
Therefore, our opposite is 24. Since our opposite equals the height of a trapezoid. We can proceed with the trapezoid formula.
[tex] \large{ \frac{1}{2} \times 15 \times 24 = 15 \times 12 = 180 } \\ \large{180}[/tex]
Therefore, the area of trapezoid is 180 units²
We can also use another method to find the area by adding up between area of triangle and area of Rectangle.
Our rectangle formula is length × width. We know width which is 4 and our length is 24 from opposite side of triangle which equal to the length of rectangle.
Length × Width = 24 × 4 = 96
Hence, the area of Rectangle is 96.
Next, we find the area of triangle which is 1/2 × base × height.
Our base is 7 and height is the opposite side of triangle which is 24.
Therefore, the area of triangle is 1/2 × 7 × 24 = 7 × 12 = 84
If we add the area of triangle and rectangle up each other, we will get the area of trapezoid for this problem which is 96 from rectangle and 84 from triangle. Therefore, 96+84 = 180 units²

Step-by-step explanation:
An art class is making a mural for their school which has a triangle drawn in the middle. The length of the bottom of the triangle is x. Another side is 9 more than three times the length of the bottom of the triangle. The last side is 7 more than the bottom of the triangle. Write and simplify an expression for the perimeter of the triangle.
Answer:
perimeter:6x+15
EXPLANATION
The perimeter of the triangle is the distance around the triangle.
We need to apply our ability to convert word problems in to mathematical expressions.
we were told that the bottom of the triangle is units.
From the diagram perimeter
Four times the length of the bottom will be .
12 more than 4 times the bottom will be
Hence another side of the triangle is
Finally we were told that the last side is 3 more than the bottom, that will be

Select the statement that describes this expression: 6 x (34,937 + 412)
A) 6 more than the sum of 34,937 and 412
B) 6 times the product of 34,937 and 412 6 times the difference of 34,937 and 412
c) 6 times the value of 34,937 + 412
Answer:
The answer is C!!! blah blah blah 20 characters long
The statement that describes the expression would be:
C). 6 times the value of 34,937 + 412.
Find the expressionAn expression is characterized as the placement or sequence in which the symbols are arranged to represent values in a group.
Given that,
Expression = 6 × (34,937 + 412)
The correct way to represent it would be:
6 times the sum produced by adding the numbers 34,937 and 412.
Thus, option B is the correct answer.

can someone help plz.....
Answer:
D
Step-by-step explanation:
Starting from the origin (0,0)
you move 4 units left and 3 units down.
That is because your given numbers are negative. When x is negative, you move left and when y is negative, you move down. The opposite goes for if your numbers are positive. Positive x , you move right and positive y, you move up.

Answer:
Third option.
Step-by-step explanation:
This is matrix addition, so we have to add the corresponding parts of the matrix correctly. The first would be 12+(-3), getting 9. The second part would be (-5)+(-9), getting up -14. Third would be 0+(-14), getting -14. Last would be (-7)+10, getting 3. So, the option with all of the correct parts in their respective positions would have to be the third option.

Answer:
In this case the number of ways would be the number of events, in this case the events would be the total number of marbles since any of them can come out. so:
4 + 3 + 3 + 2 = 12
Therefore, the number of ways the event can occur is 12 ways.
Now, in the favorable outcomes of the event, it would come depending on what color the marble would be, whether it be red, blue, yellow or green.
In each color, the number of the favorable outcomes of the event would be the quantity of each marble, that is, 4 for red, 3 for blue, 3 for yellow and 2 for green.
